As we said in the introduction, the main use of scatterplots in R is to check the relation between variables.For that purpose you can add regression lines (or add curves in case of non-linear estimates) with the lines function, that allows you to customize the line width with the lwd argument or the line type with the lty argument, among other arguments.. The larger the cex value gets, the larger is the font size. Note that I always specified the cex arguments to be equal to 3. The default value is 1. key.length: amount of space reserved for the key along its axis, length of the scale bar. R Multiple Plots. Many thanks, guys! This starts as ‘1’ when a device is opened, and is reset when the layout is changed, e.g. It is a generic function, meaning, it has many methods which are called according to the type of object passed to plot(). In this article, you will learn to use par() function to put multiple graphs in a single plot by passing graphical parameters mfrow and mfcol. This function allows you to write an image to a file as-is, so you don’t need to fine-tune all the arguments of the corresponding function.
